    Análisis de parámetros termodinámicos para determinar niveles de eficiencia en miniturborreactores
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica., 2025-02) Paucar Rojana, Christian Javier; Cabrera Anda, Santiago Paúl
    This project focuses on acquiring in-depth knowledge about miniturbojets within the field of combustion engines, since, to date, there is not enough research on the subject. An evaluation of the thermodynamic parameters that influence their operation was carried out, using specialized software. In this program, a miniturbojet model was selected and, based on it, calculations were made to optimize its efficiency and performance. For the initial development, key aspects such as the temperature and inlet and outlet pressures in the compressor, combustion chamber and nozzle were analyzed. In addition, additional variables such as fuel type and compression ratios were considered. These factors were determined by thermal efficiency calculations, considering the heat input in the miniturbojet compressor. From these parameters, an exhaustive analysis was carried out, allowing the identification of different variables that influence the performance of the system. In particular, a detailed study of the TJ1 turbomachine was carried out, in which its thermal and propulsive efficiency were determined, showing how the energy contained in the gas flow is transformed into useful thrust. In addition, it was identified that various sections of the miniturbojet operate under a Brayton cycle, which allowed its isentropic performance to be evaluated under the temperature and pressure conditions reached during the operation of the system, also considering possible energy losses and their impact on efficiency.
